We had a new patio, deck and roofing done in our Columbia home. More recently we did some backyard landscaping to complement it. Richard's father-and-son team was a pleasure to work with. Not only did they have highest quality craftsmanship at a reasonable price, Richard often came up with design and material ideas which helped to shape the project. He also has been very helpful in addressing the unexpected complications that inevitably arise in renovating an old home.

today I had a tree removed this is been one of five The price was very reasonable the job was done quickly, completely with no Mas left behind.’ I have also received an estimate for a new roof this estimate was in detail with pictures explaining everything not just verbal this is what will do and this is what the cost will be. we intend to have a roof done by R&R in the early fall but in the meantime will be getting estimates for other repairs that need to be done. you will not regret using this company that’s a realtor for over 25 years I’ve dealt with a lot of companies and this is truly one of the best.

This family business was a pleasure to work with. They came at a time of crisis for water mitigation after my sump pump died. They worked against a quick timeline and high pressure situation. They were calm, communicative, helpful and went above and beyond to ensure the repair and reconstruction process was handled with care and with top quality results. I recommended them to my mother a week later who used them right away. A++
